1.2.8 Connection of the workpiece
When connecting the workpiece ground terminals, attention must be
paid to the following:
1.
The workpiece ground terminals must be connected directly to
the workpiece or to the workpiece fixture (welding bench,
welding grid).
Steel constructions, tracks, pipelines, etc. may not be used as current
conductors, unless they are themselves the workpiece to be welded.
2.
The welding workpiece may, or may not, be connected to earth
ground.
This will vary with the user’s location/facility. A connection
from workpiece to earth ground may exist and yet not be visible or
apparent to the user.
3.
If possible, place the workpiece ground terminals at the same
distance from the point of welding when two ground clamps are
used.
Prior to connecting the workpiece ground terminals, the following advice on
avoiding arc blowing should be observed.
Note!
